The firmware driver is optional, but the power driver depends on it,
which needs to be reflected in Kconfig to avoid link errors:
aarch64-linux-ld: drivers/soc/xilinx/zynqmp_power.o: in function `zynqmp_pm_isr':
zynqmp_power.c:(.text+0x284): undefined reference to `zynqmp_pm_invoke_fn'
The firmware driver can probably be allowed for compile-testing as
well, so it's best to drop the dependency on the ZYNQ platform
here and allow building as long as the firmware code is built-in.

The zynqmp-genpd driver communicates the usage requirements
for logical power domains / devices to the platform FW.
FW is responsible for choosing appropriate power states,
taking Linux' usage information into account.

only when HAS_IOMEM is enabled.

Xilinx ZYNQMP logicoreIP Init driver is based on the new
LogiCoreIP design created. This driver provides the processing system
and programmable logic isolation. Set the frequency based on the clock
information get from the logicoreIP register set.
